[Docutils-develop] Babel without Korean

[Hoze <yi...@gm...>]

To whom it may concern,

In Babel class of the docutils.writers.latex2e module,
the language_codes variable lacks 'ko': 'korean'.

That causes a warning message, "no Babel option known for language 'ko'"
every time I run sphinx or jupyter-book.
It makes nearly no problem, yet annoying.

It'll be appreciated if you add 'ko': 'korean'.
